Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548676, here are decompositions:

17 + 31548659 = 31548676
23 + 31548653 = 31548676
83 + 31548593 = 31548676
113 + 31548563 = 31548676
149 + 31548527 = 31548676
233 + 31548443 = 31548676
353 + 31548323 = 31548676
389 + 31548287 = 31548676

Showing the first eight; more decompositions exist.
